KA-T built block
msd coil
turbonetics gtk650
850cc injectors
emance ecu
z32 maf
I can get the car to start but it will not idle
with out holding throttle open.
plugs become black.
dumping too much fuel.
at one point i took out the fuel fuse
and was able to start the car and it idled
for like five seconds real nice
on the fuel in the cylinder alone. WTF

I'm really starting to knock this tune.
spoke to Jason several times last year
and now getting back around to dealing with this,

really nobody with any ideas. This ecu is pissing me off! i already put in stock injectors and ecu and it runs fine. but with my 850cc injectors and the emance ecu= garbage.
and don't anyone say i'm knocking the tune. I have tried everything, and I do mean everything. Anyone with similar problem and their tune? What other tunes are recommended for 850cc denso injectors. Everyone so far wants to blame something else like my maf and it works with the other stuff hooked up soooooo,my case in point....emance does not work for me plain and simple money in the toilet. The guy was super cool but no results.

u deffinately need to get it tuned for cold and warm start up. running too rich will cause the motor to die. too much fuel dumping will casue the plugs to foul out. plus, u need to get the injector dead timing right on. get it on the dyno and tune it.

Oh yes. Got new ecu and car fired right up with new plugs.
